    Abstract: A method for manufacturing an electrochemical device, implementing a process for manufacturing a porous electrode having a porous layer deposited on a substrate, the porous layer having a porosity of between 20% and 60% by volume and pores with an average diameter of less than 50 nm. The method includes providing a substrate and a colloidal suspension including aggregates or agglomerates of monodisperse primary nanoparticles of an active electrode material, having an average primary diameter of between 2 and 60 nm, the aggregates or agglomerates having an average diameter of between 50 nm and 300 nm, then depositing a layer from the colloidal suspension on the substrate, then drying and consolidating the layer to obtain a mesoporous layer, and then depositing a coating of an electronically conductive material on and inside the pores of the layer.

    Abstract: Battery including at least one unit cell formed by an anode, an electrolyte, and a cathode, defining a stack. The stack of the battery has a plurality of faces that includes two end faces opposite one another, two lateral faces opposite one another, and two longitudinal faces opposite one another. The first longitudinal face includes at least one anode connection zone and a second longitudinal face of the battery includes at least one cathode connection zone that is laterally opposite to the at least one anode connection zone. In a first longitudinal direction of the battery, each anode current-collecting substrate protrudes from each anode layer, from each layer of electrolyte material or layer of a separator impregnated with an electrolyte, from each cathode layer and from each cathode current-collecting substrate layer. In a second longitudinal direction of the battery that is opposite to the first longitudinal direction, each cathode current-collecting substrate protrudes from each anode layer, from each layer of electrolyte material, or layer of a separator impregnated with an electrolyte, from each cathode layer and from each anode current-collecting substrate layer.
